devices: xhci: allow statx syscall on x86_64

Browse source 
Recent builds (starting R100.14501.0.0) crash when attaching a USB
device to the Linux VM due to calling the statx syscall, which was
missing from the seccomp policy. stat was already allowed, so add statx
as well to prevent the crash.

The change is likely due to the upgrade of the Rust toolchain in the
Chrome OS SDK (https://crrev.com/c/3439725), which landed in this build.

This was already allowed on arm/aarch64, so no other changes are
required.
